Background. Hip distraction in Perthes' disease unloads the joint, which negates the harmful effect of the stresses on the articular surfaces, which may promote the sound healing of the area of necrosis. We have examined the effect of arthrodiastasis on the preservation of the femoral head in older children with Perthes' disease. Methods and Materials. Twelve children with age more than 8 years...

INTRODUCTION Physiotherapy using muscle strengthening and stretching exercises is claimed to have beneficial effects in the treatment of Legg-Calvé-Perthes disease; however, no scientific evidence is available concerning effectiveness of treatment. PURPOSE The purpose of the present study was to clinically evaluate possible effects of the proposed physiotherapeutic effects compared to observa...

Our aim was to investigate the relationship between urinary excretion of deoxypyridinoline (DPD) as a marker of bone resorption, and Perthes' disease. There were 39 children with Perthes' disease in the florid stage who collected first-morning urine samples at regular intervals of at least three months. The level of urinary DPD was analysed by chemiluminescence immunoassay and was correlated wi...

A nationwide study of Perthes' disease in Norway was undertaken over a five-year period from January 1996. There were 425 patients registered, which represents a mean annual incidence of 9.2 per 100 000 in subjects under 15 years of age, and an occurrence rate of 1:714 for the country as a whole. There were marked regional variations. The lowest incidence was found in the northern region (5.4 p...

Coagulation parameters were studied in a population of 118 children with Perthes disease in order to determine the possible role of thrombophilia as a causative factor for the disease and to determine if thrombophilia could affect its course. We found 27 children presenting one or more coagulation disorders. The statistical analysis concurs with previous findings of a relationship between Legg-...
